To all whom it may concern:

Be it known thatl, ARTHUR HADDOOK, a' citizen of the United States,residing at East Orange, in the county of Essex, State of New Jersey,have invented certain new and of which the following is afull, clear,concise, and exact description.

This invention relates tocontact terminals and particularly tocontact-terminals adapted for useon multiple contact electricalapparatus such as dial switches, rheostat's, and the' like. g a 1 Theobject ofthe invention is. the provision of an improved contact terminalwhich may be economically manufactured andwhich may be secured to amounting plate without the use of additional parts such asscrewsorrivets. I A further object is the provision'on such a'iterminaliof suitable means for supporting,

conductors' or resistance element's.

, In accordance with the above objects, the

preferred formof the invention comprises; a flat, punched metal contacttermmal,

ada ted to be mounted edgcw'ise, provided wit a pair of integrallugswhereby itrmay be secured to a mounting plate, .-and a hopk-. shaped endmay be readi y secured.

The invention will be" better understood j from a detailed descriptionwith reference to the accompanying drawing, in which Fig.

1 is a perspective view of a dialswitch, and Fig.2 is a perspective viewof a contact terminal in accordance with the present invention.

In Fig. 1 the terminals 1 areshown arranged'in a circular row mounted ona plate of insulating material2. ,A movable conj tact 3 is attached 5 toa handle. 4 by which it may be rotated to wipe over the contact.terminals. m' v As shown in Fig. 2, the contact terminal comprises amain ody portion 1 havir ig a contacting surface 1" on "one edge. 3 W0parallel lugs 1 and 1 extend from the edge of the main portion oppositethe contacting surface 1 'A hook-shaped soldering terminal 1 is alsoprovided whereby con'jducting wires may be attached as illustrated inwill be seen from an examination of Fig. 1, the two, lugs 1 and 1 extendthrough said lugs w ortion to which aconductor said contact bein pieceof thin flat metal, t us permitting a Q large number to be usedin' arelatively small space. Itrequires no bending operation and no screws orrivets to hold it in place.

' The appended claims are not to be construed aslimited to the specificshowing as there are many, possible modifications of the i design whichwould co of the invention. I l

What is claimed is: 4 q

1.- In'combination, a perforated mountin 'plate, a metal contact, and aplurality o lugs projecting from said contact, said conme within thescope tact being secured to said plate solely by means of-one of saidlugs whose end projects plate and is distorted.

.2. In combination, a perforated mounting plate, a metal contact, asoldering terminal,

and a plurality. of lugs projecting from said contact sai' d contactbeing secured to said mounting iilatelsolely by me'ans of one of torted.

ose end projects through a'perforat1on 1n sald mounting plate and is disthrough a perforation in said mounting- 3. In combination, perforatedmounting plate, *fitflitt punched metal contact, and a plurality oflugs" projecting fromone edge of sald. contact, said contactbeingsecured to said plate solelyby means of. one of said lugs whose endprojects through a perforatlon in said mounting plate and is d storted.4. In combination, a perforated mounting plate, a flat punched "metalcontact, a solder- 1 ng term 1nal',- and a plurality of lugsproectlngtrom one edge ofsaid contact, said contact being secured tosaid plate solely by means of one of said lugs whose end projectsthrough a perforation in said mounting plate and is distorted.

5.. In a switching device, a perforated I mounting plate, a punchedmetal contact, a"

plur'ality of lugs integral with said contact, secured to said plate,

solely by meanso one of said lugs whose 7 end projectsthrough aperforation in said mounting plate and is distorted, and a solderingterminal integral with said contact and extending away from the, edge ofsaid mounting plate. v

6. Inv combination, an insulating mounting plate having perforations, aplurality of flat metal contacts, each having lugs projecting from oneedge for registering with said perforations, the edges of said contactsfrom which the ln 5 project forming a bearing surface for said.contacts, said contacts belng secured to said mounting plate solely byone of'said lugs whose end projects through said mounting plateand isupset.

7. In combination, an insulating mounting plate having perforations, aplurality of fiat metal contacts, each having lugs projecting from oneedge for registering with mounting plate solel by one of said lugs whoseend projects t rough said mounting plate and is upset.

8. In combination, an lnsulating mounting plate having rows of closelyspaced perforations therein, 'a plurality of flat punched metalcontacts, each having lugs projecting from one edge and registerinradially with said perforations, the edges 0? said contacts fromwhich'the lugs project bearing upon said mountin plate, sa1d contactsbeing secured to sai mounting plate solely by one of said lugs whose endprojects through said mounting plate and is upset;

In Witness whereof, I hereunto subscribe my name this 17th day ofSeptember A. D., 1921.
